The founding of a co-operative society in 1985 required at least fifteen people, so there were not only architects, but also specialist engineers among the members. Meanwhile, the latter set up their own companies as well, but still retained their membership in MATESZ. Even today, they provide a safe background for our work, as we can rely on them as professional and business partners. We are contracted with almost forty specialist engineers and experts, and employ them according to the scale and complexity of each project.
